A cohort of 88 patients with glottic cancer (13 Tis, 75 Ti) who underwent endoscopic
CO2 laser excision between January 1995 and June 1997 was prospectively studied.
The mean follow-up was 43 months (range, 30 to 60 months). The depth and
extent of the excision (graded according to the European Laryngological Society
Classification, which includes 5 types of resection) were based on the results
of a preoperative and intraoperative diagnostic test battery. Five patients
died of other diseases, but none of glottic cancer. Of the 12 patients who
developed a local recurrence, 5 underwent a second endoscopic procedure,
5 a total laryngectomy, and 1 a supracricoid laryngectomy, and 1 was treated
with radiotherapy. The 5-year local control rate with endoscopic surgery
alone, according to the Kaplan-Meier method, was 91%. None of the variables
(8 related to the tumor and2 to the treatment) tested in aunivariate analysis
by the log-rank test was found to have a significant impact on disease-free
survival. The present study confirmed that endoscopic partial cordectomies
for Tis-Tl glottic cancer can be regarded as valid alternatives to radiotherapy
in terms of oncological results. |
